6. Hydroxyapatite - Wikipedia

   en.wikipedia.org/wiki/Hydroxyapatite

   Hydroxyapatite is the main mineral component of enamel in teeth. [22] During demineralisation, calcium and phosphorus ions are drawn out from the hydroxyapatite. The mineral ions introduced during remineralisation restore the structure of the hydroxyapatite crystals. [22]
